Essay 1: How Do We Work With Limited Knowledge

Essay 1: How do we work with limited knowledge?

David Hume is famous for showing philosophers that we rely on induction—or the generalization of something from specific instances. For instance, Hume demonstrated that just because the sun has been rising every day for as long as humans can remember, that alone does not constitute proof that the sun will rise again tomorrow. This skeptical stance reveals that inductive reasoning, which underpins much of scientific and everyday reasoning, does not possess logical certainty but rather depends on habit and expectation. Despite the remarkable achievements of physics in describing the universe, it must admit that it cannot definitively prove the sun will rise tomorrow; rather, it relies on our repeated observations and the assumption that patterns will continue, which remains an act of informed belief rather than certainty.

The COVID-19 pandemic exemplifies how limited knowledge challenges us on a global scale. The emergence of a new virus compelled scientists, health officials, and policymakers to rapidly adapt, often operating with incomplete or evolving information. This uncertainty prompted a reassessment of previously held "truths" and highlighted the importance of working within a framework of limited certainty. Similar to Hume's assertion that our expectations are based on habit rather than logical proof, our responses to the pandemic relied on best guesses and probabilities informed by the available data. As Hume posits, human reasoning is inherently probabilistic, and embracing this view allows us to navigate uncertainty more effectively, accepting that our knowledge is always provisional and subject to revision.

In addressing the skeptic who claims that all our knowledge is essentially unknowable or unreliable, a practical approach grounded in Hume’s philosophy involves recognizing the limits of our epistemic authority while still making necessary decisions. This entails adopting a stance of cautious optimism—acknowledging the provisional nature of our beliefs, but acting on the best evidence available. Moreover, this perspective calls for humility and openness to new information, understanding that scientific theories and our beliefs are best understood as approximations rather than absolute truths. As Hume remarks, human understanding is inherently limited, and so we must live with the possibility of error, fostering a mindset that values inquiry, continuous learning, and adaptability amid uncertainty.

Human beings constantly grapple with the challenge of making decisions and forming beliefs in a world characterized by limited and often uncertain knowledge. The philosophical insights of David Hume provide a valuable framework for understanding how we navigate this landscape of uncertainty. Hume’s skepticism about induction reveals that much of our reasoning is rooted in habit rather than certainty, emphasizing that we operate in a probabilistic realm. In contemporary contexts, such as the global response to the COVID-19 pandemic, this perspective proves especially relevant, as decision-makers must rely on incomplete data and evolving scientific understanding. Embracing Hume’s view encourages humility, adaptability, and reliance on best-available evidence, recognizing the inherent limitations of human knowledge.

Hume’s skepticism underscores a core challenge: the lack of logical certainty in inductive reasoning. For example, no amount of past observations guarantees future occurrences, yet humans habitually assume continuity based on experience. This has profound implications for science, public policy, and everyday life, where decisions must often be made despite incomplete certainty. The pandemic exemplifies this dilemma: policymakers, scientists, and the public had to act on evolving evidence, knowing that their beliefs might later be revised. Such reliance on probabilistic reasoning aligns with Hume’s assertion that human understanding is fundamentally limited and that our beliefs are based on habit, custom, and experience rather than demonstrable certainty (Hume, 1739/1978).

Addressing the skeptic who dismisses all knowledge as unreliable requires an acknowledgment of epistemic limitations coupled with practical pragmatism. Hume’s philosophy entails that we accept our finite understanding and act based on the best available evidence, while remaining open to revision. This pragmatic approach fosters resilience and humility, enabling us to function effectively even amidst substantial uncertainty. For instance, during the pandemic, public health measures such as vaccination campaigns and social distancing were grounded in the best available scientific reasoning, despite the acknowledgment that future data could alter current understanding. By adopting this outlook, we balance the necessity of decision-making with the awareness of our epistemic boundaries, cultivating a mindset that values ongoing inquiry and adaptation.
